Default Re: adding weight to a piston

We learn by doing and making mistakes. Back in the day we'd cut the bottom of the piston off at the bottom ring, balancing was never an issue, Unfortunately there wasn't anyone around that did that. Bells in Patterson NJ did it for 80 dollars I think. I built a balancer for rods and pistons that allowed me to find parts that are equal. The Janns Pistons we used were all over the map and we got pretty good with a die grinder on the balance ring in the bottom of the piston. When It gets a little warmer I'll dig that stuff out and post it. You don't need a scale. Considering all the "Stuff" we did to these engines and got away with it, makes me realize what a great engine it is. I'm sure a precision but one would last forever. Take care Elwood.

Ellwood, if you use locktite use the right one..maybe this one, read the discriptions then decide. you might not need any with a press fit.

I know the Canadian & US 59A wrist pins were a different weight The pistons were different weight too,but the combined weight of piston & pin were the same.

what would be wrong with filling the pin with J.B.Weld and then the excess weight could be drilled out to precisely what you need?

What would be wrong with putting 8 matched pistons in, instead of a cobble job that may come apart and ruin a good flathead block? Just my thought. Marv

I'd be more concerned with wondering when the seven remaining pistons were go to start cracking.....

That's a hell of a lot of work to have to do over again.... and again... and again.
